SPECIFICATION forming part of Letters Patent No. 767,660, dated August 16, 1904.

Application filed December 6, 1901. Serial No. 84,894. (No model.)

, To all whom it may concern:

Be it known that we, WILLIAM G. PRIon and EDGAR PnoKHAM,resicling at Kingston, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Trucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to trucks; and its object is to provide means for lubricating the swivel plates or slides in constructions wherein a car-body is supported upon the trucks by means of a swivel-plate connected to such car-body supported upon and having a slid ing connection with a second plate supported upon the truck-frame.

To this end our invention consists in the devices, combinations of elements, and arrangement of parts which will be more fully set forth hereinafter and the novel features thereof defined in the claims at the end of this specification.

The invention will be understood by reference to the embodiment thereof shown in the accompanying drawings, in which Figure 1 is a longitudinal sectional view showing conventionally the wheels and part of the frame of a truck with the parts which constitute our invention shown in detail. Fig.

2 is a top plan View of the upper swivel-plate.

with the oil-cup attached thereto. Fig. 3 is a transverse sectional view of a truck with our invention applied thereto on line 00 m of Fig. 1 looking in the direction of the arrow.

Similar reference characters refer to similar parts throughout the several views.

In the drawings we have shown our invention as applied to a well-known type of maximum-traction trucks, such as are adapted to be used in pairs under a car-body, each truck having one set of large wheels and one set of comparatively small wheels, the' weight of the motor being carried by the large wheels, together with the greater part of that of the car-body, which car-body is adapted to be attached to and is supported by a swivelplate which cooperates with a second swivelplate supported upon the bolster of the truck. It will be understood, however, that we are not limited to such construction, as our invention can be used in connection with a variety of trucks, whether of the type shown or other types, so long as it is desired to properly lubricate the supporting swivel-plates or to apply the pressure in different degrees to. the different wheels of the truck. The lubricant-cup may be supported in various ways and in various positions with relation to the swivel-plates, and various methods of feeding lubricant from said cup to the bearing surface or surfaces of the plates may be used without departing from the spirit of ourinvention.

The illustration and description herewith are simply intended as a preferred embodiment.

Referring first more especially to Fig. 1, A represents one of the side frames of a maximum-traction truck, of whichB represents the axles, and O and D, respectively, are the large and small wheels. Transoms E are properly supported upon theside frames, and a bolster F is guided between such transoms and may be supported in the usual way upon elliptic and spiral springs. (Not shown.) Aspring-plank composed of two spaced bars Gr, set on end, is supported by links Ha pair at each end of the transomwhich links are supported on pivot-pins it, resting in castings 70, secured to the transoms. Pins 7L pass through both members of the spring-plank and are journaled in the links H ateach end.

The parts thus far described are of known construction and are illustrated only as an aid to the illustration of parts which constitute our invention. A bar or casting f is supported by rivets within the bolster F, and a pivot pin or rod f is supported in cars or lugs f uprising from said bar f, a single lug only being shown in Fig. l. A lower swivelplate K, carrying the kingpin 7c, is hingedly supported at its inner end upon the transverse pin f by lugs or ears it, through which said transverse pin passes loosely. An upper swivel plate L, having pivotal movement about the king-pin is provided with a transverse vertical flange or cross-plate L, to which any suitable part of the car-body, as a bodybolster in the usual construction, is adapted to be bolted, so that it is supported by the swivel-plate inside of said flange. Lugs L L are likewise provided in the upper swivelplate beyond the circumference of the lower plate, through which attaching-bolts may be passed. It will be understood that, if desired, instead of having the cooperating faces of the two swivelplates smooth, as shown herein, they may be provided with tongue-and-groove connections, which connections would act as centering devices to properly center the car even if the king-pin were omitted. A groove Z in the top of the swivel-plate L leads from a hole through the transverse plate to a vertical hole Z, which communicates with the upper surface of the lower swivel-plate. In front of the transverse attaching-plate L is located a lubricating-chamber or oil-cup N, which may be attached in position in any suitable way, as by a clip or strap a, as here shown, which passes around said truck and is connected at its ends to the plate L. Tube n connects the groove Z with a chamber a in the center of and opening into the oil-cup. Wick n is adapted to carry the oil from the oil-cup to said chamber, whence it willpass by the tube and groove to the point where it is to be applied between the two swivel-plates. It will thus be seen that we provide a construction such that the lubricant-chamber is situated at the side of the car-body bolster where it is cleared by the lower cross-beams of the car-body in their movement pivotally with relation to the truck, and the connecting-passages are such that a constant regular flow of lubricant to the surface between the swivelplates is assured. If desired, any other method of regulating the flow of oil from the lubricant-chamber rather than that of capillary attraction, as shown, may be used.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a car-truck, in combination the axles, wheels, frame and swivel-plates, and means for lubricating said plates carried above said plates and at one side of the point of attachment of the car-body thereto.

2. In a car-truck, in combination the axles, wheels, frame, and swivel-plates adapted to support a car-body pivotally upon said frame, an oil-cup carried above said swivel-plates and at one side of the point of attachment of the car-body thereto, and means for conveying oil from said cup to the bearing-surfaces of the swivel-plates.

3. In a car-truck, a frame, upper and lower swivel-plates supported the one on said frame and the other adapted to be attached to the car body, and means for lubricating said swivel-plates comprising an oil-cup supported adjacent thereto, a groove in one of said plates communicating with the bearing-surfaces between said plates, and means for feeding oil from said cup into said groove.

4:. In a car-truck, the frame, upper and lower swivel-plates supported the one on said frame and the other adapted to be attached to the car-body, and means for lubricating said swivel-plates comprising an oil-cup supported adjacent thereto, a groove in one of said plates communicating with the bearing-surface between said plates, and a wick in said cup for carrying oil to said groove.

5. In a car-truck, the frame, upper and lower swivel-plates supported the one on said frame and the other adapted to be attached to the car-body, a vertical flange extending transversely of the upper plate on one side of which the car-body-supporting beam rests, an oil-cup carried by said plate on the other side of said flange so as not to interfere with the car-body attachment, and means for feeding oil from said cup to the bearing-surface between said swivel-plates.

6. In combination the truck-frame, swivelplates K, L supported thereon, flange L and grooves Z in connection with plate L, oil-cup N carried in front of said flange, and means for feeding oil from said cup to said groove.

7. In combination the truck-frame, swivelplates, K, L supported thereon, flange L and groove Z in connection with plate L, oil-cup N carried in front of said flange, tube a communicating with the interior of said cup and with groove Z, and wick n for feeding oil from said cup to said tube.

8. In atruck-frame, a swivel-plate supported on said frame for movement relative thereto, and means for lubricating the bearing-surface of said plate comprising a lubricant-chamber supported adjacent thereto and means for feeding the lubricant from said chamber to said bearing-surface.

9. In a car-truck, a frame, a swivel-plate supported on said frame for movement relative thereto, and means for lubricating the bearing-surface of said plate comprising an oil-cup supported adjacent thereto and a wick for feeding oil from said cup to said bearingsurface.

In testimony whereof we aflix our signatures in the presence of witnesses.
